Macadamia nut is known as the "king of dried fruits", with shallow root distribution and weak wind resistance. The suitable temperature is 10-30℃, and the optimum temperature is 15-30℃. Lower than 10℃ or higher than 30℃ is not conducive to nut growth.
When the rainfall in that year was1000-2000mm, the effect was better. When the rainfall is below 1000 mm or in arid areas, the growth is slow, the fruit becomes smaller, the development is poor, and the fruit drop is serious.
Extended data:
Planting should avoid dry, rainy and high temperature seasons, and plant in the early or late rainy season to facilitate the recovery of plant growth. Planting density varies with soil conditions and variety types.
Generally, the plant spacing is 4m× 5m, 33 plants are planted per mu, and more than 25 plants are put into production per mu; Yunnan, on the other hand, advocates different varieties, with plant spacing of 4m× 7m, 4m× 8m and 4m× 9m, and planting 18 to 24 plants per mu.
The specifications for digging holes are 0.8×0.8×0.6 (m). Most macadamia nuts are largely self-sterile, so the varieties planted should be crossed (different varieties should be crossed and planted alternately), and at least two varieties should be matched in one plot.
